  • Pressurization system for fire extinguishers
    Patent number: 7082999
    Abstract: A fire extinguisher includes a gas generator for pressurizing a suppressant. The generator includes an ignition cord within a flexible tube extending within an interior of an extinguisher bottle. Advantageously, there is additional generant between the tube and the ignition cord. The extinguisher may be manufactured as a retrofit of an existing hand-held supercharged extinguisher.

  • Hybrid fire extinguisher
    Patent number: 6702033
    Abstract: A discharge valve element seals the outlet of a fire extinguisher vessel holding a fire suppressant. A source of gas pressurizes the suppressant at least when the extinguisher vessel is in a discharging condition. When the pressure acting on the element exceeds the threshold, the force resisting opening the element is overcome and substantially eliminated, whereupon the suppressant discharges through the outlet.

  • Fire extinguisher
    Patent number: 6612243
    Abstract: An apparatus for fire suppression may include a flexible container, a gas generant or other suppressant, initially located within the flexible container, and an initiator. A propagating member may be located within the container to permit the initiator to initiate the generant or expel the other suppressant upon triggering of the initiator to extinguish the fire. A sustainer may be provided to sustain the suppression and may be positioned within a generator housing upstream of the propagating member or at or adjacent the downstream end of the propagating member.
